Be it known that I, ALBERT A. DAY, a citizen yof the -'United States, residing atthe :borough of Brooklyn, in the county of Kings,

" cityfand State of New. York, have invented `certain new and useful. Improvements in AMetal--Frarne Window-Screens; and `I do hereby declare the following tobe afull, clear, and exact description of theinvention, such as will enable others skilled in the art to My invention consists in the novel features hereinafter' described, `reference being had to .bodying my invention, and said invention is i fully dlsclosed'in thefollowing description `and claims.

Referring to thesaiddrawings, Figure 1 represents a perspective view o`f a sliding extensi- -ble screen embodying'rny invention. Fig. 2

of a -`smaller equipment` of tools, maf chlnery, & c., than wouldbe i:c'iiired to produce panels differing in formjuch as are ordinarily used'in the' manufacture of sliding A6o extension-screens.

a `number ofscreen Vpanelsor sections ex, actly `alike and provide them with 4means whereby two or more may he placed in `en 6 5 gagement-with each other and interlocked in such a manner that when in position in the' opening of a window-casing theyinay be made to slide horizontally with respect to each other to fit the particular window ,in 7o which theyare employed.

My invention contemplates the `use of screen sections or panels which are so conf structed thatthey may be placed in engagement and interlocked in such a `manner that they will remain in the interlocked position uwhen in use, by gravity, lin which case such section or panel is. provided with aguiding and interlockmg flange on one horizontal side only to embrace or engage the' opposite edge 8o ofthe adjacent section; but I may. also provide the sections with variouslformsof interlocking devices, as hereinafter described, so f that While the sections may -be'interlocked they are permanently held together and will notbe` liable to be separated'whenthe screen isremoved from the Window,

L also contemplate forming the'separate sections with a metallic folded sheet-metal frame formed in one vcontinuous piece and in- 9o closing marginal JI p ortions'on allsides of the piece of screen abrio, as .described inniy prior a plie-ation, filed August 22, 1906,` and given erial No'. 331,645, and my inyention also provides for making the ycontinlfijoiis me- 9 5 tallic frame4 of greater width atfcertaln *portions of its length, so as to makeone or both' eater` width than the lateral verticalframe- ,ar s,tofprov1de the interlockingdevices hereinafter described. `In formingone of my improved screenpanels I take a stripof sheet .metal of such width that wl'ien foldedlongitudinally'it will provide the desired width for the frame-bars `and of suiicient `length to extend 4entirely around thefour sides or ledges of thescreen and preferably extend several inchesbeyond. This strip is-thenv folded i longitudinaliy. (usually `in lthe 'centerf, valthough thisis not essen- 1 i o tial) or .Vd/ as-it is terrified.,` A rectanofu According ,to my invention IymanufactureI orming the roo v.be accomplished bye placingthe beading, stamping, or crimping machine, and l and s'o on until the screen fabric is completely w when considerablay I `therefore employ a beading-machine to form a longitudinally-extending bead running substantially the whole length of the sideof the screen fabric, as shown at X, Fig. l of the drawings, this Vbead being formed in the two sides of the frame-bar and also to inclose the screen fabric, and thereby securely fastenin 'the sere'en fabric -within the folded bar.v -T ie folded frame-bar is then bent at right .anvles to the beaded portion, so as to inclose the next adjacent side or edge of the screen fabric and the metal at the corners crimped or attened down in any suitable 4manner and by any suitable machine or tool, so as to form a screen which may be perfectly rectangular or slightly rounding at the c orners, as preferred. The folded strip is then secured to the adjacent side of the screen fabric in like manner, the next corner turned,

inclosed Within the one piece-folded metallic frame.

InFigs. 1 and 2, A represents the screen fabric, and B the folded one-piece frame formed and applied in the manner just described and secured to the screen fabric by the beads X or equivalent means. As reviously stated, I make the strip of fo ded metal which forms the frame longer than nec,- essary, and I permit the ortioii last secured tothe fabric to extend eyond the edge of the screen to form an extension, which is indieated at -b in Figs. l1 and 2. The edge of this extension projects beyond the vertical edge of the screen-section at one side of the saine, sol that when two of these screen-sections are interlocked, as is lierenafter'described, the extension b of each will extend into the guiding and retaining flange of the other and assis't in guiding the l'raines in their lateral slidin` movements, particularly extended. After the frame 1s formed, as before described, and as set forth in my. prior application, before referred to, I forin the interlocking means, whereby two of such sections exactly alike may be intcrlocked to make a sliding extension-screen. v-

In Figs. l, 2*," and 3 I have shown one forni in which I have contemplated embodying my invention, in which one frame-bar of each section or panel is left exactly asit is after the fabric is secured, the opposite frame-bar beingbent longitudinally to form an mter- 'locking' guiding and retaining Bange, (indicated at' b in those fifures,) which receives the plain frame-bar o the adjacent section. In assembling two of these panels, as shown in Figs. 1, 2, and 3, it is only iiecessai'y to place them together, with the flan e b of -ene section dropped over the plain e ge of the second'section and the plain edge of the first section dropped into the flange b of the sec- 'f frame-bar being slightly sma ler than the.

bent ortion of the other frame-bar, as illustrateil) at b 118 in Fig. 10. Two exactly siini lar screen-sections of the frame shown in this figure can be interloeked in the saine inanner as the sections shown in Figs. l, 2, and 3 and will remain in hplace by gravity while in use. y

Obviously in using a sliding screen constructed iirsections or panels, such as are shown in Figs. l, 2, 3, and l0, the screen-sections may become detached when not in use, and I therefore contemplate providing the sections with interlocking portions which will permit the screen-sections to be assenibled and at the saine time will prevent them from being separated in any way, except by drawing lthem out horizontally to diseiigage the interlocking portions. Such a construction is shown in Fig. 4, in which each screen section or panel has one horizontal frame-bar provided with a hook-shaped longitudinally- In Fig. 10 I have shown a slightmodifiea IOO IXO

extending guiding and retaining flange l1 and the o posite frame-bar is provided with a perpen( icular flange b3, lof such form as to interlock and fit within flange b2 of another section br panel, as clearly indicated-in said figure. Fig. 5 shows another construction of this character, in which one horizontal frame-bar of each sectionV or panel is bent, as

shown, to form a guiding and retaining fiange b4, and the opposite frame-bar is given ano tuse angular bend to frame' of flange b,

which interlocks and fits within the flange b of anotherexactly. similar. section, as clearly shown in tTiatiigure.\ ,While I have shown thesearticularforins,I dofnot wish to be limited) exact] longitudinal portions of various eongurations within the scope of my invention.

It is obvious that with reference to all of i 2 5 thereto, as I may form the rame -bars with interlocking moese the forms' of screen panels or sections-'herein y. shown and i described I may employ two,-

three,- or even more sections, if necessary," to

"\fit `within vtheopening" of windows 'having nor'e than ordinary width, and vthus' obviate y the necessity of making' the screensectionsor `panels',themselves of varying 'widthsto ac' commodate particularlyfwidewindoweopenings.

In bending overl one or both horiicontal frame-bars or' therscreen sectionor` panel the width'- ofl theframe-bar 1s somewhat narrowedmetry. and appearance of thc-.framewhen not in'use.- In? orden' to avoid this, I in some cases form one or both `of the. lportions'v ofth'e:

frame Whichforni the horizontal members -orbars Wider thanfthe remaining.por-t1ons, 's0 vas.

.bending and after the interlockingv and.3,in.whichthe sections are each made in thisv lmanner. v Eachwsectivon or' panel c omprises the screen fabric Al and theonepiece metallic frame B,-inclosi-ng theledges of the fabric and secured thereto; as previously described. In this instance the blank from whichv the frame is -made isformed wider at `the `portion intended to be used in bending 4 .fthe retaining-Harige b, as illustrated in Fig. 7

at el; an'ddfig. 8 shows the blank after it has been "folded longitudinally Vd. Fig. 9 shows a completedscreen-section as it would appear before bending the flange b, and it will be noticed that the horizontal frame-bar (indicated atc and formed by the Wider ortionsy of the blank) is of such Width that j@ o en the flange b has been' formed by be dingjas indicated by the dotted line c', ghe said" frame-bar will be of the same `Width as the other frame-bars. While I have shown in Figs. 6 to 9, inclusive, the one framebar having this increased Width', itA isobvious that more than one 4portion of the continuous metal strip may be made Wider, as described.

In some .cases it isdesirable, after the screen composed of two or more of the sections, as herein described,have been extended so as to fit Within a Wide Window-opening, to

p casing.

lock the sections permanently together and prevent them from slidingl ponyeach other.

This can be readily accoiinp ished by giving a blow with a hammer or othe tool upon the retaining-flanges at one or m re'points,so'as to bend theminward and cau e theml to clamp the `inclosed framebar. to 4tlhe adjacent secy understood.,v In some instances it; is alsbe desirable tov se',` cure the screen rigidlyvyithin the' ,window'f' In Figs. 11 to .4 Ihave shown a means for accomplishingthis result applied to a two-panel` screen cof,l osed of sections similar to those shown in igs. 1, 2, and3;
